<blockquote>
<p>
If your web application uses URL rewriting rather than cookies to save session information,
then you'll need to do a bit of extra work to test your site.
</p>
<p>
To respond correctly to URL rewriting, JMeter needs to parse the HTML
received from the server and retrieve the unique session ID.  Use the appropriate 
<a href="../usermanual/component_reference.html#HTTP_URL_Re-writing_Modifier">HTTP URL Re-writing Modifier</a>

to accomplish this.  Simply enter the name of your session ID parameter into the modifier, and it
will find it and add it to each request.  If the request already has a value, it will be replaced.
If "Cache Session Id?" is checked, then the last found session id will be saved,
and will be used if the previous HTTP sample does not contain a session id.

<p>

<a href="../demos/URLRewritingExample.jmx">
this example
</a>
. In Figure 1 is shown a 
test plan using URL rewriting.  Note that the URL Re-writing modifier is added to the SimpleController,
thus assuring that it will only affect requests under that SimpleController.

<p>
In Figure 2, we see the URL Re-writing modifier GUI, which just has a field for the user to specify
the name of the session ID parameter.  There is also a checkbox for indicating that the session ID should
be part of the path (separated by a ";"), rather than a request parameter

The

JMeter sends in the HTTP request header.  This header includes properties like "User-Agent",
"Pragma", "Referer", etc.
